METALLIC RAILROAD-TIE.

Specification of Letters Patent.

Patented J une 7, 1910.

Application led. October 14, 1909. Serial No. 522,591.

To all whom it may concern:

Be` it known that I, ALWL S. VARREN, a citizen of the United States, and a resident of Batavia, in the county of Genesee and State of New York, have invented a new and Improved Metallic Railroad-Tie, of which the following is a full, clear, and eX- act description. v

The purpose of this invention is to provide a metallic railroad tie having novel details of construction that render the tie light, strong and durable, and prevent the tie from creeping endwise, or sinking into the roadbed; a further object is to provide a novel, simple and very effective means for securing track-rails upon the improved cross ties, that may be readily released for track repairs and quickly re-secured, as occasion may require.

The invention consists in the novel construction and combination of parts, as is hereinafter described and defined in the appended claims.

Reference is to be had to the accompanying drawings forming a part of this specilication, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a plan view of the improved tie and rail clamping means thereon; Fig. 2 is a partly sectional side view of details, substantially on the line 2 2 in Fig. 1; Fig. 3 is an enlarged transverse sectional view of the improved tie, and a side view of the improved rail clamp and rail thereon, the section being taken substantially on the line 3 3 in Fig. 1; Fig. 4 is a perspective view of a plate metal chair, that is a detail of the invention; and Fig. 5 is a perspective view of a novel cushion plate employed.

The body of the improved cross tie consists of two plates 10 and 11, that are rightangular considered endwise, these similar portions of the tie being secured together so as to give them T-shape in cross section, by lapping two members thereof and clamping them in that condition by a plurality of rivets a. The tie body further consists of a fiat top plate 12 that is seated and secured by rivets a on the horizontal members of the right an ular portions 10 and 11, thus greatly rein orcing the tie body against strains in all directions.

At suitable points, preferably equally distant from the ends of the right angular'- portion 10 of the cross tie body, angular bent plate metal wings 13 are secured, that project outwardly, these wings serving to anchor the tie body in a roadbed, and prevent its longitudinal creeping movement when embedded therein for service.

Means are provided for securing two track rails 14 of usual T-shape upon a plurality of the improved cross ties that are spaced apart on a proper roadbed, the preferred construction of said means, that constitute important features of the improvement, consisting of the following details for each track rail and cross tie.

A liner or cushion plate 15, preferably formed of vegetable fiber board is provided, which is imposed upon the top plate 12 of the cross tie at a point which will locate it below a track rail 14 when said rail is properly positioned on the cross tie.

As clearly shown in Fig. 5, the cushion plate 15 is formed of a flat planchet of the material specified, having an oblong rectangular form, the side edges being respectively recessed as shown at b and o, the forms of which will be hereinafter fully described.

Upon the cushion plate 15, a plate metal chair 16 is seated, said mainly liat plate having nearly the same size as that of the cushion plate 15, and a rectangular form, having on one side edge thereof at respective corners, two similar upwardly projected flanges CZ formed thereon, as shown in the drawings. The flanges el have contact with the lateral edge of a base flange 14a on a track rail 14, said base flange being outermost when the track rail is in position on the cross ties.

A clamping block 17 rests upon the top plate 12, adjacent to one iiange Z on the chair 16, and said block is fitted into a rectangular recess b formed in the outer side edge of said chair, which is positioned directly over the similar recess l) in the cushion plate 15, and it will be noted that the relative position of the clamping block serves to prevent longitudinal displacement of the plates 15 and 16. As shown, the clamping block 17 is shaped so as to fit against the outer side of the track rail 14, and bear upon the web and lower side of the ball or head of said rail, and is secured in place upon the top plate 12 by two bolts e and nuts e thereon.

A clamping block 18 is positioned on the top plate 12 at a point that disposes it opposite the notch or recess o in the cushion plate 15, and likewise opposite a similar notch or recess c that is formed in the chair 16, and located directly above the recess c, when the chair is in proper posit-ion. The clamping block 18, that is disposed opposite the innermost base flange 141 on the track rail 111, is shaped in its clamping member g so as to bear upon the flange 14h, and thence said clamp extends of sufficient length, said extended portion engaging the topplate 12, as is clearly shown in Figs. 1 and 2. An offset `is formed Where the clamping member g is joined With the extension of the clamp, providing` a shoulder g thereat. A reinforcing clamp 19 coperates With the clamping block 18 for retention of the track rail clamped upon the top plate 12, said clamp 19 comprising a flat member h that` is seated upon the extension member of the clamping block 1S, and at its free end engages the offset shoulder g the heel portion of the reinforcing clamp seating upon the top plate 12.

Tivo bolts z', z" are provided for securing the clamping block 18 and reinforcing clamp 19 in engagement with the top plate 12, and base flange 14.1), the bolt z' passing through the clamping member It, block 18, and top plate 12, While the bolt z" is inserted through the heel of the reinforcing clamp 19, and the top plate 12, said bolts all being provided with nuts for their clamping service.

It will be noted in Figs. 4 and 5, that the recesses c and c in the normally inner side edgesof the cushion plate 15 and chair 16 are each. formed With a concave defining edge c2.

To prevent the member h on each reinforcing clamp 19, from turning laterally in case the nut on the bolt z' becomesslackcned, a. small rib g2 is formed on the upper side of the clamping block 18, near the shoulder g said rib seating in a correspondingly shaped depression formed in the under side'of the member it, near its free end. It

will be seen that when the member h is clamped upon the clamping block 18, by

nuts on the bolts z', if, the clamping block and reinforcing block will be rigidly se cured together', and neither one of them can turn laterally, until the bolts z', z" are loosened sufliciently to permit the reinforcing member L to ride over the rib g2 with which it. was engaged; It Will be understood that each of the clamping blocks 18, and reinforcing clamps 19 are provided With the locking device that hasibeen described.

When the clamping block 18 is arranged for service, it occupies the registering recesses c and c in the plates 15 and 1G, and said block along with the reinforcing clamp 19 will rigidly secure the track rail 14 on the top plate 12, When the nuts on the bolts z' and z" are properly adjusted for. such a purpose, due to the engagement of the rib g2 in the recess in the reinforcing clamp 19.

As indicated in F ig. 1, the clamping block 18 is adapted for lateral rotatable adjustment if the clamping bolts z' and z" are loosened by an unscrewed adjustmenty of the nuts thereon, the concave edges c2 of the recesses c and c permitting said clamping block to be rocked laterally on the bolt z' as a pivot, When the member It of the reinforcing clamp is free to ride over the rib g2.

It will be apparent that the meansj ust described, for securing the track rails on the improved cross ties, enables their secure connection, and also permits a release of the track rails ifv this is desired. Furthermore the cooperating of the cushion plate 15, chair 16, rail 14', and improved cross tie is such, that While the track rail isheld firmly against lateral displacement, a proper elasticity is afforded between the crossetiesand track rails by rolling stock, which will reduce Wear and iender travel on the road more comfortable.

Having thus describedV my invention, I

claim as new and desire to secureby Letters- Patent:
